| Controller
|
Description |
| Control
Functions: |
Dual
PID+: two independent, event-selectable sets of control functions for each channel consisting of proportional, integral and derivative
control plus reset windup inhibit and reset clipping. "Set
2" tuning is in effect when the enabling event is ON. Cycle
time ranges from 2 to 15 seconds. |
